Could some one point me to at what I'm doing wrong in the config.yml?

I'm following the tutorial and the advent stuff and trying to enable plack_middlewares.

Here's my config.yml

layout: "main"

charset: "UTF-8"

template: "template_toolkit"

engines:

template_toolkit:

encoding: 'utf8'

start_tag: '[%'

end_tag: '%]'

log: 'debug'

show_errors: 'true'

plack_middlewares:

Debug:

- panels

- Memory

- DBITrace

- Timer

Here's the error message when I plackup

$ plackup -S Starman --workers=10 -p 5000 -a bin/app.pl

Thanks for any help!
